Specification forming part of Letters Patent No. 115,553, dated May 30, 1671.

To all whom it may concern:

I, Gnonen W. Mmnnnn, of Charlottetown, Queens county, Prince Edward Island, have invented a certain new and useful Improvement in Seed-Drills, of which the following is a complete specification:

Not-me and Object of the Invention.

Description of th-eDrawz'ng.

Figure 1 is a perspective View of my invention. Fig. 2 is a vertical section of the same. Fig. 3 is a perspective View of one of the seeddistributers.

General Description.

The wheels, frames, thills, 820., of my seeddrill are made as shown in the drawing, or in any desirable manner which shall accommodate the operating parts of my invention. 0 is the seed-receptacle, and extends entirely across the frame from wheel to wheel. From the lower side of the seed-receptacle C a series of tubes, D D, extend downward, as shown. Between the upper ends of these tubes and the lower side of the box 0 a plate, P, is arranged to slide back'and forth, and is provided with holes corresponding with those made in the lower side of the box 0, the whole so arranged, in connection with the pipesD and the handle or lever P, that, by the.

movement of this handle, all the openings in the box 0 may he opened or closed by one moi ement. B, Fig. 2, is a shaft extending through the seed-box, and is provided with a number of downwardly-projeotin g arms, B which serve as agitators to prevent the seed from clogging.

Motion is given to the shaft B by the arm B link B crank-pinion B and the gear B.

Each one of the seed-tubes D has connected with it a sliding extension, 01, which enters into a cross-tube, D This cross-tube D is triangular in section, its lower angle serving, when the machine is in operation, to make a small drill or furrow for receiving the seed. E E are triangular coverers hinged to the part D at E their function being to cover the seed after it has been deposited. 1)

D 850., is a series of sliding rods, to the lowor ends of which the cross'tubes l) D are attached. These rods D slide on frictionrolls K K, on standards L L, 850., Fig. 2, which are attached to a swinging frame, H. Each one of the rods D is attached to the shaft 1) by the chain D, so that if the shaft 1) is caused to revolve the rods 1) will be drawn up, taking with them the cross-tubes D and the extension (1. The shaftD is made to revolve by the segmentgear I) and lover D". The frame H is attached to the axle-tree M by the hinge N.

The position of the frame H may be changed by lengthening or shortening the chain S.

The operation of my machine is as follows: The receptacle (3 is first filled with seed to be sown, the opening 0 in the lower part of thebox being closed by the slide P, and the cross-tube or driltmaking tube being drawn up. In this condition the machine is ready for the field, and may be drawn as readily as a wagon. \Vhen itis desirable to sow, the cross or drill-making tubes D D 850., may be lowered so as to come in contact with the ground, and the orifices c in the lower part of the seed-box may be opened, so that the seed may fall into the tubes D, and then through the extensions (1 and the cross-tube D tothe drill. As this takes place while the machine is in motion the coverers E E will immediately draw the earth back into the drill.

Claims.
